Description

CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. provisional application Ser. No. 62/290,639 filed Feb. 3, 2016, the disclosure of which is hereby incorporated in its entirety by reference herein.
TECHNICAL FIELD
The present disclosure relates to culvert arrangements, and more particularly to a culvert pipe inlet that permits the entire flow of water entering into an end section of a pipe of a culvert inlet or downspout to prevent slope erosion and wash out.
BACKGROUND
Downspout pipes and culvert inlets experience a reoccurring problem with respect to accommodating water runoff from roadways and ditches. More specifically, current designs require metal end sections to be installed with the unit wrapping around the outside of a pipe. As a result, this installation allows for water to flow between the outside of the pipe and the metal end section and follow the grade down the pipe causing the materials used to cover the pipe to wash away. This wash causes slope erosion and can develop into an unsafe condition for the roadway. These conditions also result in high maintenance costs and wasted man-hours repairing the same location repeatedly. What is needed is a culvert arrangement that reduces slope erosion and requires less frequent maintenance efforts.
SUMMARY
In one exemplary arrangement, a culvert pipe inlet arrangement for culvert pipes is disclosed that comprises an inlet section and a pan member. The inlet section is connected to the first end of the pan member. The inlet section has a diameter less than an internal diameter of a culvert pipe such that the inlet section is configured to be received in frictional engagement with an interior surface of the culvert pipe.
In another exemplary arrangement, a culvert pipe inlet arrangement for use with culvert pipes comprises a pan member, an inlet section and a sleeve. The pan member is defined by first and second ends and a body portion between the first and second ends. The inlet section is connected to the first end of the pan member, but has a continuous diameter. The sleeve has first and second ends, wherein the first end is smaller than the second end such that the sleeve is tapered, and wherein the second end of the sleeve is secured to the inlet section.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is top plan view of a culvert pipe inlet arrangement;
FIG. 2 is a plan view of a band member for the culvert pipe inlet arrangement of FIG. 1;
FIG. 3 is a plan view of an inlet section of a culvert pipe inlet arrangement of FIG. 1;
FIG. 4 is a plan view of a second embodiment of a culvert pipe inlet arrangement;
FIG. 5 is an elevational view of a sleeve for a circular pipe; and
FIG. 6 is top plan view of the culvert pipe inlet arrangement, with the sleeve mounted thereto.
 DETAILED DESCRIPTION
As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
Referring to FIGS. 1-3, a first arrangement of a culvert inlet 10 is illustrated. Culvert inlet 10 comprises a pan member 12 and an inlet section 14. The pan member 12 includes a first end 16 and a second end 18 with a body portion 20 therebetween. The pan member 12 flares outwardly from the first end 16 to the second end 18. In one exemplary arrangement, the pan member 12 has a bell shape. The body portion 20 includes a planer surface positioned between upwardly extending side walls 22 that may terminate in rolled edges 24 to provide additional rigidity to the pan member 12. The first end 16 of the pan member 12 is fixedly secure to the inlet section 14 such that the culvert inlet 10 is a unitary element.
Referring to FIG. 3, the inlet section 14 is generally configured with a shape that generally corresponds to the shape of a standard culvert pipe. For example, as illustrated in FIG. 3, inlet section 14 is generally configured with a circular cross-section. A portion 26 of the inlet section 14 may be removed from the inlet section 14 to allow selective movement of ends 28 a, 28 b of the inlet section 14 toward one another, to produce a smaller inlet section 14. More specifically, unlike prior art culvert inlets, the inlet section 14 is inserted into a culvert pipe. By removing portion 26, the inlet section 14 may be partially collapsed to allow easy insertion into the culvert pipe. In one exemplary arrangement, due to the configuration of the inlet section 14, a spring force of the inlet section 14 will cause the inlet section 14 to conform to the interior surface of the inlet section 14 and engage via friction fit.
In an alternative arrangement, once the inlet section 14 is disposed within the culvert pipe, a spreader rod 30 may be inserted into the inlet section 14. And exemplary arrangement of a spreader rod 30 is shown in FIG. 2. Spreader rod 30 includes a linear section 32 that includes two threaded ends 34 a, 34 b. A tightening sleeve 36 receives the threaded ends 34 a, 34 b therein. In operation, the tightening sleeve 36 may be rotated in a first direction to force the threaded ends 34 a, 34 b away from one another and outwardly from sleeve 36 expand the perimeter of the spreader rod 30 to secure the inlet section 14 against the interior surface of the culvert pipe. To remove the inlet section 14 from a culvert pipe, the tightening sleeve 36 may be rotated in a second direction to collapse the spreader rod 30 and remove the spread rod 30. Once removed, the inlet section 14 may be slide outwardly from the culvert pipe.
Referring to FIGS. 4-6, a second embodiment is illustrated of a culvert inlet arrangement 100. Culvert inlet 100 is similar to culvert inlet 10 in that it comprises a pan member 112 and an inlet section 114. The pan member 112 includes a first end 116 and a second end 118 with a body portion 120 therebetween. The pan member 112 flares outwardly from the first end 116 to the second end 118. In one exemplary arrangement, the pan member 112 has a bell shape. The body portion 120 includes upwardly extending side walls 122 that may terminate in rolled edges 124 to provide additional rigidity to the pan member 112. The first end 116 of the pan member 112 is fixedly secure to the inlet section 114.
Culvert inlet arrangement 100 further comprises a sleeve 125, which is illustrated in FIG. 5. The sleeve 125 comprises first and second ends 127, 129. First end 127 has a diameter D1 that is slightly smaller than a diameter D2 of the second end 129. This configuration results in sleeve 125 being slightly tapered. Adjacent to second end 129 is a section 139 that bulges outwardly. Section 139 serves as a stopper when in use. Second end 129 receives inlet section 114 therein and second end 129 is fixedly secured to the pan member 112, such as by welding, as shown in FIG. 6.
In operation, the sleeve 125 is inserted into the culvert pipe 150. Due to the tapered configuration of the sleeve 125, the sleeve 125 may easily be inserted into the culvert pipe. Section 139 may set against the open end of the culvert pipe to prevent debris from entering between the sleeve and the culvert pipe. The sleeve 125 is then fixedly secured to the culvert pipe, by suitable fasteners, to limit movement of the sleeve 125 within the culvert pipe.
The designs of the culvert inlets 10, 100 allow for the entire flow of the water entering the end section 18, 118 to flow unimpeded into the flowline of the culvert pipe. This is accomplished by installing the culvert inlets 10, 100 into the pipe instead of on the outside. This will keep the water from washing around the outside of the pipe and direct the flow of the runoff to the desired outlet, thus limiting excessive erosion.
While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention. Additionally, the features of various implementing embodiments may be combined to form further embodiments of the invention.
